Overvoltage protection by crowbar technology
High noise immunity - static dV/dt > 500 V/µs
AC ON/OFF static switching in appliances and
industrial control systems
Drive of low power high inductive or resistive
loads like:
– relay, valve, solenoid,
– dispenser, door lock
– pump, fan, micro-motor
Needs no external protection snubber or
varistor.
Enables equipment to meet IEC 61000-4-5.
Reduces component count by up to 80%.
Interfaces directly with the micro-controller.
Common package tab connection supports
connection of several alternating current
switches (ACS) on the same cooling pad.

Description
The ACS108-6S belongs to the AC line switch
family. This high performance switch can control a
load of up to 0.8A.
The ACS108-6S switch includes an overvoltage
crowbar structure to absorb the overvoltage
energy, and a gate level shifter driver to separate
the digital controller from the main switch. It is
triggered with a negative gate current flowing out
of the gate pin.

... AC line switch - basic application 2 AC line switch - basic application The ACS108-6S switch is triggered by a negative gate current flowing from the gate pin G. The switch can be driven directly by the digital controller through a resistor as shown in Figure 13. Thanks to its overvoltage protection and turn-off commutation performance, the ACS108-6S switch can drive a small power high inductive load with neither varistor nor additional turn-off snubber ...

... AC line transient voltage ruggedness The ACS108-6S switch is able to withstand safely the AC line transients either by clamping the low energy spikes or by breaking over under high energy shocks, even with high turn-on current rises. The test circuit shown in is also used to test the ACS switch according to the IEC 61000-4-5 standard conditions. ...
